Bosch Therm Concentric Vent Kit (ESHCK)The Bosch Therm Concentric Vent Kit (ESHCK) is a stainless steel concentric vent kit that allows for a single-wall 5" penetration through the side wall combining both the exhaust and the air intake. This kit can only be used if the Bosch Therm tankless water heater is installed on a wall that is perpendicular to the wall through which the heater will be vented due to its length.
This concentric stainless steel vent kit must be combined with a 3" piece of vent pipe that is at least 3' in length and a 3" termination tee and a 90 degree elbow. We sell all of these pieces together as the ESHCK-FULL-KIT.This Concentric Side-wall Vent Kit is designed to work with the Bosch Therm 940ES, Bosch Therm 830ES, GWH 715ES and Evolution 500 as well as the Bosch AquaStar 2700ES and 2400ES heaters.
